The Muscle Brake was designed to be extremely shooter friendly. With the first port being 90 degrees it shears the back blast off from the angled ports, to prevent the "blast/concussion" effect from distracting the shooter. These brake are made of 416SS, and hardened to 30 Rockwell. Benefits to the Muscle brake are increased recoil reduction, no back blast to the shooter as compared to typical angle port and radial port brakes, and the brake to barrel joint can be tapered and blended for a seamless appearance.
